Yunyinggu (Viewtrix Technology)

Yunyinggu Technology (云英谷科技), which rebranded as Viewtrix Technology, is a Shenzhen-based fabless semiconductor company founded in 2012 that designs AMOLED display driver integrated circuits (DDIC) and color-rendering display solutions for smartphones and other devices. By 2024 sales volume it was the largest AMOLED display driver chip supplier in mainland China and the fifth-largest globally, with R&D and operations across Shenzhen, Shanghai, Beijing, and Hong Kong. Backed by Qiming Venture Partners (Series C and extension), Huawei, and Xiaomi, the company completed a Hong Kong IPO. It is a hardware/semiconductor business and publishes no public developer API surface; this profile is retained as a network identity record. The original yunyinggu.com domain no longer resolves and viewtrix.com is a parked domain-for-sale listing.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/yunyinggu: open an issue to ask a question, or submit a pull request to add artifacts.
